Hi! One of our users recently requested that wolfSSL become compatible with Mongoose. As such, we have recently made changes to the wolfSSL 1.5.4 embedded ssl library to make it build seamlessly with the Mongoose embedded web server. Essentially this meant that we made minor enhancements to wolfSSL’s openssl compatibility layer to accomplish a clean build. Everything should build cleanly at this point, but let us know if you face any issues. If you build with wolfSSL instead of OpenSSL, you will get a smaller resulting build. You can contact us with any support issues you face at info@yassl.com.
